NextJSON

NextJSON - parse, format, edit and export JSON with ease!

What it does

NextJSON is a fast, privacy-first Chrome extension for working with JSON. Paste raw JSON into the popup to instantly parse and format it, or let it auto-format any JSON page in your browser. Explore data in Tree, Raw, Graph, Table, or UI Preview views, run JQ/JSONPath queries, search with regex, and edit inline with undo/redo. Fetch from URLs (custom methods + headers), diff payloads, and export to JSON, CSV, Excel, YAML, or TypeScript. Light & dark themes.

    Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
